What this case file preserves

The file retains the selected observations, query read times, methods and available source lineage. It is not a complete government source archive. Search links rerun current data. Sharing a JSON file preserves the collected values. Browser storage can be cleared; download a copy to retain it.

01Source records

DOL filings, WARN notices and contract actions retain their own units and dates.

02Calculated comparisons

Date windows, wage comparisons and employer-ID joins use the rules below.

03Inference limits

Timing, a wage difference or a linked employer ID does not establish replacement or misconduct.

Methods, coverage and interpretation

One result is one certified H-1B LCA. The selected date basis filters source submission or DOL decision dates, never ingestion or confirmed hiring. Results are ordered by that date, newest first.
Date basis: DOL decision date. 2026-01-01 through 2026-12-31, inclusive.
Known quality-flagged filings are excluded from this search under the existing filing-browser rule. Their raw records remain in the archive. Missing required dates, links or wage values cannot establish a match.
Search method: investigation-search/2.
For the same canonical employer ID, the LCA submission date must be within 90 days before or 90 days after a WARN effective date, including both endpoints. The nearest matching notice is shown; all matching notices are counted.
LCA worksite and WARN notice must be in the same state.
Same-state matching is not a same-worksite or same-job match. WARN occupation comparability is not established here. Positions requested are not unique workers or confirmed hires. Overlapping dates do not prove replacement.
